Error parsing XML: no element found

Question

First off forgive me if I posted this question wrong. I've used stackoverflow for many problems but this is the first time I couldnt already find an answer to my problem. So, if I'm doing something wrong please let me know and I'll repost / edit the question.

Now unto business. I've just recently started development w/ the Android SDK and I'm following the basic tutorial from http://developer.android.com/resources/tutorials/hello-world.html#avd I've gotten up the xml editting part and when I make all the changes to the xml files main.xml and strings.xml this error occurs. Also, when I compile the project, the compilation process generates a main.out.xml file that is empty. I don't know what it is or its purpose.

The error:

[2011-12-30 16:10:02 - Hello Razor] res\\layout\\main.xml:0: error: Resource entry main is already defined. [2011-12-30 16:10:02 - Hello Razor] res\\layout\\main.out.xml:0: Originally defined here. [2011-12-30 16:10:02 - Hello Razor] C:\\Users\\Dux69\\workspace\\Hello Razor\\res\\layout\\main.out.xml:1: error: Error parsing XML: no element found [2011-12-30 16:10:13 - Hello Razor] Error in an XML file: aborting build.

My project is setup for platform: Android 2.3.3 API Level: 10

I don't know if it makes a difference or not but I'm using my Android Incredible for running/debugging the application not a Android Virtual Device. If there is any more information needed let me know and I'll post it ASAP.

Here are the three code files I'm using:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView  xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/textview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" 
android:text="@string/hello_O" />

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello_O">Baba in the house, Razor Activity!</string>
<string name="app_name">Hello Razor App</string>
</resources>

razorActivity.java

package hello.Razor;

import android.R;
import android.app.Activity;
import android.os.Bundle;

    public class razorActivity extends Activity
    {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState)
        {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.main);
        }
    }

Answer 1

I had a similar problem once.

Rebuilding/cleaning the project and restarting Eclipse helped for me.

Answer 2

删除项目视图中的main.out.xml并重新运行为android应用程序

Answer 3

Error message I got:

Error:(43) Error parsing XML: no element found

and

Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: Failed to execute aapt

Solution: In my case, project activity_main.xml is initiated with the code

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.batvibes.battybirthday.Main1Activity">

and I forgot the below end tag.

</android.support.constraint.ConstraintLayout>

Disclaimer: I am totally new to android development. My suggestion, please check all tags opening and closing and go to next step of debugging.

尝试结束您的主要或子布局，如：
